i have these calipers and they are stamped with BMW 60/28/302 ATE. Can someone confirm which car it came from. Thanks.

These calipers are from a 740 or a 540. The code means the following: 1) 60 is the diameter of the piston 2) 28 is the thickness of the rotor 3) 302 is the diameter of the rotor. So this means that it is a 302x28 rotor, which comes on the 740 and 540 and the 60mm piston is consistent with the front calipers from those cars.
Hope this helps,
Rob

Good info to know!
What about rear calipers with 38/10 toward the center?

38 means 38mm piston bore. 10 means 10mm thick rotor, which would be a solid rear rotor. As for which car these came on, I would have to do some more research as you are missing the last number.
Hope this helps,
Rob
